概括

由于时间限制和过去的经验,许多医疗保健工作者对COVID-19疫苗增压剂犹不决. 接受两次强剂的人抗体水平最高,显示了额外剂量的益处.

科学领域:

免疫学免疫学免疫学
流行病学流行病学
公共卫生公共卫生

背景情况:

由于COVID-19大流行,需要快速开发针对SARS-CoV-2的疫苗.
新兴的关注变种 (VOC) 和疫苗接种覆盖率不均导致反复出现的浪潮.
医疗保健工作者 (HCW) 对额外的COVID-19疫苗剂量表现出犹,影响公共卫生战略.

研究的目的:

调查导致COVID-19增剂疫苗在HCW中犹的因素.
在HCW中进行强剂疫苗接种后分析抗SARS-CoV-2 IgG抗体反应.

主要方法:

调查评估疫苗犹的原因.
在接种疫苗后测量抗SARS-CoV-2 IgG抗体标位.

主要成果:

42%的HCW表示对第二剂补充剂犹;7%打算不再接种疫苗.
犹的主要原因包括缺乏时间,过去的负面疫苗接种经验,以及从先前感染中感知到的免疫力.
在未接种疫苗的HCW中观察到最低的抗体标位,而在接受两次增强剂的人群中观察到最高的抗体标位.

结论:

医疗保健工作者对疫苗的犹受实际和经验因素的影响.
补充疫苗接种,特别是多剂量,显著增强了抗SARS-CoV-2IgG抗体反应.
解决犹和促进增强剂的吸收对于对不断演变的SARS-CoV-2变种的持续免疫力至关重要.

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
